What is HAProxy Kubernetes Ingress Controller?

Nine months into the 3.2 line, HAProxy Ingress is still repairing ssl-passthrough and ingress merge order.

The controller ships a steady patch cadence on the 3.2 branch, roughly one release every two to four weeks. Content is almost entirely correctness work: ssl-passthrough handling and the rules that decide which Ingress object owns a shared backend. Feature additions are absent from the last ten releases; dependency bumps to k8s.io and golang.org/x packages appear in most of them.

What is Strimzi?

Strimzi's 1.2.0 candidate closes with a logging fix and nothing else

The 1.2.0 release cycle has reached its second candidate, and it is a small one: a single fix for incorrect CA logging on top of rc1. Everything substantive in this release landed in rc1 — Kafka 4.3.1 support, per-pod volume templates, and server-side apply now permanently enabled. This feed publishes only release candidates and never the finals, so an rc is the record of what shipped.

HAProxy Kubernetes Ingress Controller vs Strimzi: editorial side-by-side

H2.5

Nine months into the 3.2 line, HAProxy Ingress is still repairing ssl-passthrough and ingress merge order.

◆ Current state

The controller ships a steady patch cadence on the 3.2 branch, roughly one release every two to four weeks. Content is almost entirely correctness work: ssl-passthrough handling and the rules that decide which Ingress object owns a shared backend. Feature additions are absent from the last ten releases; dependency bumps to k8s.io and golang.org/x packages appear in most of them.

◆ Where it's heading

v3.2.13 is the largest release in the window and marks a shift from patching individual ssl-passthrough bugs to defining the semantics properly: backends are now reconciled rather than recreated, the invariant is applied before anything that can fail, and controller-owned backend state survives a failed transaction. Alongside it, ingress merge order became deterministic — oldest ingress first — and the first Ingress to constitute a backend now owns it, with the annotations a losing Ingress forfeits named explicitly. That pairing suggests the team traced a class of flapping and non-reproducible config bugs back to undefined ordering.

◆ Prediction

Expect the next few releases to stay on the 3.2 patch line, adding tests around the new ownership and passthrough invariants rather than new annotations.

Strimzi's 1.2.0 candidate closes with a logging fix and nothing else

◆ Current state

The 1.2.0 release cycle has reached its second candidate, and it is a small one: a single fix for incorrect CA logging on top of rc1. Everything substantive in this release landed in rc1 — Kafka 4.3.1 support, per-pod volume templates, and server-side apply now permanently enabled. This feed publishes only release candidates and never the finals, so an rc is the record of what shipped.

◆ Where it's heading

Post-1.0 Strimzi is spending its cycles on how the operator manages Kubernetes resources rather than on new Kafka surface. ServerSideApplyPhase1 has gone alpha to GA and is now always on, and 1.2.0 changes install-time defaults toward Restricted Pod Security Standard security contexts and volume-mounted Service Account tokens. A second candidate carrying one logging fix says the cycle is converging rather than still absorbing change — the CRD v1-only requirement from 1.0.0 remains the loudest thing in every release body.

◆ Prediction

Expect 1.2.0 final shortly with no further candidates, and the next cycle to advance one of the open feature gates — UseBackgroundPodDeletion is the likeliest to move from alpha to beta.
